- Well .. Yes and no and then no and yes!? Read on, the point gets clearer!
-
- Developers can certainly use a barrier or two .. as they are more likely
- to run/test code with errors. On the other hand .. (most) developers
- are aware of this and take extra care when in this mode. They are less
- likely (if at all) to lose data.
-
- "End users" (I suppose) should be less likely to execute code with errors.
- This would seem (at first) to indicate that protection is not (is less)
- necessary(?). On the other hand ... (many) "End users" will likely get
- caught by the unexpected error and will be more likely (in this case) to
- lose information/data.
-
- Time is another consideration and is certainly a good reason to have the
- extra protection, for both developer and end user.
-
- Overall, I would have to say that, it's more important (in general) not
- to lose data. I think it's the "End user" that is more likely to be caught,
- resulting in loss of data. For this reason, "End users" need this
- protection more.
-
- This is not an all or nothing area. It's clear (IMO) that both developer
- and "end user" can benefit quite a bit by having this protection, even
- though efficiency is (at times) sacrificed.

- We all go through this one, but I'm sure it wasn't my fault.
